Decide 226 is a tuning shop in Japan since 1995. They build and put their work to the test by racing them.
Visit their site here: http://www.decide226.co.jp/ I can’t seem to find any mention of this car on their site. They have some links and posts with content of this car but that’s it.
Decide 226 Suzuki Cara
I used to have more info on this but I can’t seem to find it. It was in regards to the modifications they have done to the F6A motor. Yes this thing is still powered by a F6A!
Engine Output: 180PS / 178HP
Mods: (Posted by Autogiano https://autogiano.com/list/ma/list_mstb2.html)
A tension rod using a pillow ball was added to the suspension to suppress unstable movement of the suspension.
This Cara model has a 660cc engine, but the turbine has been replaced and NOS has been added.
The RB26 crank angle sensor has been transplanted and controlled by HKS VPro.
The transmission is a Works R cross transmission.
Initially, the piston pin, piston ring TOP, oil ring, and rocker arm were DLC coated, but after the piston was replaced due to an engine blow, the rings were not coated.
I think it would be better to coat the piston pin.
The cam is a Tomei processed product, and is standard plus 8 degrees.
The transmission is WPC processed.
I heard that hard shot peening is actually better, but for now it hasn't broken with WPC (lol).
The hub has been changed to PCD100 and the hub bolt has been changed to 12mm.
Tires: Yokohama A050 F185/55/15 R225/50/15
